billboard collision detection
Author
hey, if im using billboards to show projectiles(lasers or whatever), what shape should i use to approximate it for collision detection. i wanted to use a cylinder, but cylinder/box intersection is tough.
thanks for any input

How is cylinder/box collision detection tough? It''s just a sphere-sphere and box-box test.
Using a Sphere is very easy (I use it for bullets in a game I am workign on for instance). A Oriented Box is good though, try that.

thanks dirge. i guess what i really wanted to know is what other ppl use, but for some reason i wanst too articulate (gee, what could possibly have been the problem?).
could you explain how to do that cyl-box test u talked about? i cant seem to see it. i can do box-box and sphere-sphere tests.

Haven''t done them in a while but I believe the cylinder test is a box-box test, then sphere-sphere. That order. This is because a cylinder has characteristics of both.

Look for the cylinder intersection tests.
